Getting Started: Installing the Sensor and
Charging the Power Stick
WARNINGWARNINGWARNING
DO NOT OPERATE THIS INSTRUMENT IN THE PRESENCE OF GASOLINE,
NATURAL GAS, PROPANE, OR IN OTHER COMBUSTIBLE ATMOSPHERES.
The Compass Refrigerant Leak Detector is shipped with the heated diode sensor packed
separately. The sensor is located in the protective foil package along with a desiccant capsule
to keep it dry. Installation of the sensor in the leak detector is required before use. To install the
sensor:
1. Locate the end of the leak detector probe and tip protector. The tip protector should be in the
detector's storage case. The three sockets in the end of the probe are for the leads of the
sensor to fit into.
2. Remove the sensor from its protective foil package. The sensor is the small metal "can" with
a hole in the top.
3. Carefully align the three leads (the small wires coming out of the bottom of the can) on the
sensor with the three sockets in the end of the probe. Insert the sensor leads into the sockets
and gently press in the sensor until the leads are no longer visible.
NOTE: You must be careful not to bend the sensor leads because this can cause erratic
operation (see Troubleshooting.)
4. Place the tip protector (with filter installed) over the sensor and tighten snugly by turning the
cap in a clockwise direction, being careful not to overtighten.
5. The nickel/metal hydride power stick is not yet charged. To charge it, connect the cord of the
AC power adapter to the power jack and plug the adapter into the appropriate outlet. Allow
10 hours for a full charge. The Compass does NOT have a fast charge feature.
NOTE: You should expect 5 hours of operation from a fully charged power stick. Some
batteries perform best after several full charge/discharge cycles. The Compass
will operate off the AC power adapter. Connecting the supplied AC power adapter
will allow operation of the detector while the power stick charges. You do not have
to discharge the power stick completely before recharging it; there is no "memory"
effect to the power stick.
Using Your INFICON Compass
WARNINGWARNINGWARNING
FAILURE TO OPERATE THIS INSTRUMENT IN THE MANNER INTENDED BY
INFICON MAY RESULT IN PERSONAL INJURY.
Using the Compass Refrigerant Leak Detector is simple: Press the control button to turn the
instrument ON. The green ON indicator LED will illuminate and all of the yellow leak indicator
LEDs will illuminate. When the yellow LEDs extinguish and the instrument beeps at a rate of
about one beep per second, the instrument is ready to use.
